Zoo Maned Wolf Kidney Disease Welfare

Maned wolves are prone to a serious kidney disease caused by a parasitic nematode - health monitoring and diet management are critical.

Key Facts

Maned wolves are the largest canid in South America with characteristic long legs for savannah living
They are omnivorous with an unusual dietary reliance on the wolf apple (lobeira fruit)
Giant kidney worm (Dioctophyme renale) infection causes severe and often fatal kidney disease in captive maned wolves
The parasite is transmitted through earthworms - diet management reduces exposure risk
Regular ultrasound monitoring detects infection earlier allowing treatment before permanent kidney damage
Wild maned wolves face habitat loss from Brazilian cerrado conversion to agriculture

Welfare Considerations

Kidney worm disease in captive maned wolves is a significant welfare challenge that requires proactive dietary management and regular health monitoring. The availability of wolf apple or equivalent foods appears linked to gut health outcomes. Zoos keeping maned wolves require specific protocol-driven monitoring programmes.
